Question

study the graph below and answer the questions. A.Calculate the velocity of the body as it moves for time interval (1)0 to 5s
,(2)5s to7s
and (3)7s to 9s.
B.Calculate the average velocity during the time interval 5s to 9s​

Answer 1

The answers of the following questions are:

(A)

(1) The velocity for time interval 0-5 s = Displacement/ time

⇒ The velocity for time interval 0-5 s = 3/5

⇒ The velocity for time interval 0-5 s = 0.6 m/s

(2) The velocity for time interval 5-7 s = Displacement/ time

⇒ The velocity for time interval 5-7 s = 0/2

⇒ The velocity for time interval 5-7 s = 0 m/s

(3)The velocity for time interval 7-9 s = Displacement/ time

⇒ The velocity for time interval 7-9 s = 4/2

⇒ The velocity for time interval 7-9 s = 2 m/s

(B)

Average velocity = Total distance/ total time

⇒ The average velocity for time interval 5-9 s = 4/4

⇒ The average velocity for time interval 5-9 s = 1 m/s

Answer 2

Answer:

B.Calculate the average velocity during the time interval 5s to 9s
